As illustrated in FIG. 1, an electronic device 1 of an embodiment is,for example, a notebook personal computer. The electronic device 1comprises a flat rectangular first body 2 and a flat rectangular secondbody 3. The first body 2 and the second body 3 are connected by a hingemechanism 4 to be relatively rotatable about a rotation axis Ax betweenan open position (FIG. 1) and a closed position (not illustrated).Hereinafter, for the sake of convenience, the width direction(horizontal direction) of the second body 3 will be referred to as “Xdirection”, the direction to the edge of the second body 3 will bereferred to as “Y direction”, and the thickness direction of the secondbody 3 will be referred to as “Z direction”. X, Y, and Z axes areperpendicular to one another.

The first body 2 is provided with a keyboard 5 as an input device, apointing device 7, a click button 8, and the like, which are exposed ona front surface 2 b as the outer surface of a housing 2 a. On the otherhand, the second body 3 is provided with a display device 6 such as aliquid crystal display (LCD) panel as an electronic component, which isexposed on a front surface 3 b as the outer surface of a housing 3 a.When the first body 2 and the second body 3 are in the open position,the keyboard 5, the display device 6, and the like are exposed to allowthe user to use them. On the other hand, in the closed position, thefront surface 2 b closely faces the front surface 3 b, and the keyboard5, the display device 6, the pointing device 7, the click button 8, andthe like are covered between the housings 2 a and 3 a. Incidentally,FIG. 1 does not illustrate all keys of the keyboard 5 but only keys 5 a.

The second body 3 is shaped in a rectangle that is long in the Xdirection and short in the Y direction in a plan view from the Zdirection, and is thin and flat in the Z direction. The second body 3comprises a housing 3 a. The housing 3 a comprises a first divisionalbody 3C and a second divisional body 3M. The first divisional body 3Chas a bottom wall 3 d that forms a back surface 3 c. The seconddivisional body 3M has a top wall 3 e that forms the front surface 3 b.An opening 3 f is formed in the center of the front surface 3 b (the topwall 3 e) of the second divisional body 3M, and a display surface 6 a ofthe display device 6 is exposed from the opening 3 f.

As illustrated in FIG. 2, the display device 6 is rectangular in a planview from the Z direction. The display device 6 is attached atsubstantially the center of the first divisional body 3C. The locationof the display device 6 is defined by brackets 6 b provided to the fourcorners of the display device 6 or the like with respect to the firstdivisional body 3C. The display device 6 has a relatively thin (heightin the Z direction) and flat shape.

As illustrated in FIGS. 2 and 6, a cable 9 is routed in an elongatedarea between a side surface 6 c of the display device 6 and an outerwall (periphery wall) 3 g of the first divisional body 3C. The outerwall 3 g is raised in the thickness direction (the Z direction) and isformed in a rectangular frame along the periphery of the second body 3.A plurality of the cables 9 (for example, three cables) may be routed inparallel depending on the location. The cable 9 may be, for example, anantenna cable.

As illustrated in FIGS. 2 and 4, a plurality of ribs 10A, 10B, and 10Care provided between the outer wall 3 g and the side surface 6 c of thedisplay device 6. In the embodiment, the three types of ribs 10A, 10B,and 10C, which are elongated along the outer wall 3 g in a plan view,are arranged linearly spaced apart from each other along the outer wall3 g. As illustrated in FIGS. 5 and 6, the ribs 10A, 10B, and 10C areprovided on an inclined boundary wall 3 h between the bottom wall 3 dand the outer wall 3 g of the first divisional body 3C. The ribs 10A,10B, and 10C protrude in the Z direction (the thickness direction of thesecond divisional body 3M) in substantially parallel to the outer wall 3g. The ribs 10A, 10B, and 10C each have an inner surface 10 a and anouter surface 10 b. The inner surface 10 a faces the side surface 6 c ofthe display device 6, while the outer surface 10 b faces an innersurface 3 j of the outer wall 3 g. The ribs 10A, 10B, and 10C arelocated near the side surface 6 c of the display device 6 compared tothe outer wall 3 g. A gap gd between the inner surface 10 a of the eachof the ribs 10A, 10B, and 10C and the side surface 6 c of the displaydevice 6 (see also FIG. 9) is substantially constant. Accordingly, in aplan view from the Z direction as illustrated in FIGS. 2 and 4, the ribs10A, 10B, and 10C and also their inner surfaces 10 a are arranged insubstantially a straight line, and the inner surfaces 10 a are locatedon a virtual plane spaced apart in parallel from the side surface 6 c ofthe display device 6. In other words, the ribs 10A, 10B, and 10C alignedin a straight line are located to face the side surface 6 c of thedisplay device 6 with the small gap gd therefrom.

As illustrated in FIGS. 5 and 6, in a place where the ribs 10A, 10B, and10C are located, the cable 9 is routed in gaps ga, gb, and gc (see FIG.5) between the ribs 10A, 10B, and 10C and the outer wall 3 g.

When, for example, the electronic device 1 accidentally falls off, thedisplay device 6 may move in a direction approaching the outer wall 3 grelative to the housing 3 a due to the inertial force acting on thedisplay device 6. In such a case, the ribs 10A, 10B, and 10C have thefunction of absorbing the impact load on the display device 6. That is,when the electronic device 1 falls off, if the display device 6relatively moves toward the outer wall 3 g along with the deformation ofthe periphery of the brackets 6 b and other parts, the display device 6may come in contact with the ribs 10A, 10B, and 10C. In the embodiment,the display device 6 in contact with the ribs 10A, 10B, and 10C deformsthem by pressure. This deformation absorbs energy, thereby alleviatingthe relative impact load on the display device 6 from the housing 3 a(the outer wall 3 g, the ribs 10A, 10B, and 10C, etc.).

The ribs 10A, 10B, and 10C further have the function of protecting thecable 9 routed between the display device 6 and the outer wall 3 g. Thatis, as described above, when the electronic device 1 falls off, if thedisplay device 6 relatively moves toward the outer wall 3 g along withthe deformation of the periphery of the brackets 6 b (see FIG. 2) andother parts, the display device 6 may come in contact with the ribs 10A,10B, and 10C. In the embodiment, even in such a case, the ribs 10A, 10B,and 10C located between the display device 6 and the cable 9 preventsthe cable 9 from being damaged by, for example, coming in contact withthe display device 6, being stuck between the display device 6 and outerwall 3 g, or the like.

In view of preventing damage to the cable 9, preferably, the ribs 10A,10B, and 10C are not substantially inclined due to pressure caused bythe relative movement of the display device 6. For this reason, in theembodiment, as illustrated in FIGS. 7 and 8, protrusions 3 i are formedin the second divisional body 3M as stoppers to stop the ribs 10A, 10B,and 10C, and the like (in the embodiment, only the rib 10A).

As illustrated in FIGS. 7 and 8, the second divisional body 3M has thetop wall 3 e and an outer wall (periphery wall) 3 k. The top wall 3 e isformed in a flat rectangular frame having the rectangular opening 3 finside it and forms the front surface 3 b of the second body 3. Theouter wall 3 k is raised in the Z direction (the thickness direction ofthe second body 3) on the periphery of the top wall 3 e. The protrusions3 i that stops the ribs 10A, 10B, and 10C are arranged spaced apartinside the outer wall 3 k, and protrude in the Z direction along theouter wall 3 k. The protrusions 3 i are formed elongated in the Ydirection.

As illustrated in FIG. 9, the protrusion 3 i extends from the edge sideto base side of the rib 10A (from up to down in FIG. 9) in the gap gabetween the outer wall 3 g of the first divisional body 3C and the rib10A. In the view of the X direction (the horizontal direction in FIG.9), the protrusion 3 i overlaps the edge of the rib 10A. Accordingly,when the rib 10A is pressed by the display device 6 and inclined outward(to the left in FIG. 9), the edge of the rib 10A is stopped by theprotrusion 3 i. After the protrusion 3 i stops the rib 10A, the rib 10Ais not likely to be inclined. This prevents damage to the cable 9 routedin the gap ga caused by an interference with the rib 10A. Note that theprotrusion 3 i as a stopper is only required to stop the rib 10A beinginclined or about to be inclined pressed by the display device 6, anddoes not need to stop the rib 10A while the display device 6 is notmoving relative to the housing 3 a.

As illustrated in FIG. 9, in the embodiment, the outer wall 3 k of thesecond divisional body 3M is located adjacent to the outside (the leftside in FIG. 9) of the outer wall 3 g of the first divisional body 3C.With this, a boundary PL between the first divisional body 3C and thesecond divisional body 3M on the side surface is located on the side ofthe back surface 3 c of the second body 3, i.e., at a position distantfrom the user who is using the electronic device 1, which improves thevisual appearance. Suppose that the display device 6 moves to theoutside (to the left side in FIG. 9) relative to the first divisionalbody 3C when the electronic device 1 falls, and the rib 10A is inclinedoutward (to the left side in FIG. 9) and engages the protrusion 3 i, andthe display device 6 further relatively moves to the outside (to theleft side in FIG. 9). In this case, if the second divisional body 3Mmoves outward relative to the first divisional body 3C together with theprotrusion 3 i, the protrusion 3 i cannot perform its function. In theabove arrangement of the outer walls 3 k and 3 g, the outer wall 3 g ofthe first divisional body 3C does not constitute an obstacle to theoutward movement of the second divisional body 3M. In view of this,according to the embodiment, second protrusions 3 m are provided insidethe outer wall 3 k of the second divisional body 3M as second stoppersthat engages the outer wall 3 g, as illustrated in FIG. 10. When thedisplay device 6 moves to the outside (to the left side in FIG. 9)relative to the first divisional body 3C when the electronic device 1falls, and the rib 10A is inclined outward (to the left side in FIG. 9)and engages the protrusion 3 i, and the display device 6 furtherrelatively moves to the outside (to the left side in FIG. 9), the secondprotrusion 3 m engages the outer wall 3 g. Accordingly, the seconddivisional body 3M is prevented from moving outward relative to thefirst divisional body 3C. Thus, it is possible to avoid the situationwhere the second divisional body 3M moves outward relative to the firstdivisional body 3C together with the protrusion 3 i, and the protrusion3 i cannot perform its function.

As illustrated in FIG. 7, The second protrusions 3 m are arranged spacedapart along the outer wall 3 k. In the embodiment, the secondprotrusions 3 m are arranged correspondingly to spaces between the ribs10A, 10B, and 10C, and does not extend into the gaps ga, gb, and gcbetween the ribs 10A, 10B, and 10C and the outer wall 3 g. This isbecause if the second protrusions 3 m extend into the gaps ga, gb, andgc, the space to route the cable 9 is reduced. As illustrated in FIG. 8,the second protrusions 3 m are formed higher than the protrusions 3 i.

A description will now be given of each of the ribs 10A, 10B, and 10C.As illustrated in FIGS. 4, 5, and 9, a convex reinforcing rib 10 c isprovided on the side of the outer surface 10 b of the rib 10A as areinforcing member to increase the rigidity and the strength. In theembodiment, the rigidity and the strength of the rib 10A is the highestamong the ribs 10A, 10B, and 10C. This is because, if the display device6 moves relative to the outer wall 3 g while being inclined, withrespect to the rib 10A that is located at the end of the array and hasthe adjacent ribs 10B and 10C on only one side, the load is lessdistributed, and a heavier load may act thereon from the corners of thedisplay device 6. The inner surface 3 j of the outer wall 3 g is formedflat. The flat inner surface 3 j prevents the cable 9 from beingconcentrically-loaded, which reduces damage to the cable 9.

To overcome a heavier load, the protrusion 3 i is provided as a stoppercorrespondingly to the rib 10A located at the end of the array. Morespecifically, in the state where the first divisional body 3C and thesecond divisional body 3M are assembled, the protrusion 3 i is insertedin the gap ga between the rib 10A and the outer wall 3 g. A gap ge isformed between the rib 10A and the protrusion 3 i. Accordingly, when therib 10A is pressed by the display device 6 and inclined, energy isabsorbed by the deformation of the rib 10A until the rib 10A is stoppedby the protrusion 3 i.

A space (the gap ga) between the rib 10A and the outer wall 3 g islarger than that between the rib 10B and the outer wall 3 g. In otherwords, a larger space is secured in which the cable 9 is allowed tomove. This prevents damage to the cable 9, and also compensates forreduction in the space by the protrusion 3 i inserted in the gap gabetween the rib 10A and the outer wall 3 g.

As illustrated in FIGS. 4 and 5, the convex reinforcing rib 10 c isprovided also on the side of the outer surface 10 b of the rib 10B toincrease the rigidity and the strength. The inner surface 3 j of theouter wall 3 g is also formed flat.

The gap gb is smaller than the gap ga between the rib 10A and the outerwall 3 g. The smaller gap gb increases the capability of retaining thecable 9, which prevents the cable 9 from deviating from the originalroute. The rib 10B is located in the middle of the array, and thereforethe load is likely to be distributed and low compared to that on the rib10A. Accordingly, even if the gap gb is smaller than the gap ga, it ispossible to reduce damage to the cable 9.

The outer wall 3 g is partly recessed at a portion facing the rib 10B asa recessed portion 3 p. If the gap gb is formed smaller than the gap gawhile the outer wall 3 g is formed in a straight shape, the rib 10Bneeds to be positioned outside the rib 10A or formed thicker. It is notpreferable to position the rib 10B outside in view of shock absorption.Meanwhile, it is not preferable to form the rib 10B thicker because itresults in an increase in the weight. Regarding this point, according tothe embodiment, the rib 10B can be easily aligned with respect to therib 10A separated from the outer wall 3 g by the larger gap ga.Moreover, by providing a convexo-concave surface to the outer wall 3 g,the rigidity of the outer wall 3 g can be improved.

As illustrated in FIGS. 4 and 5, between the rib 10C and the outer wall3 g, a vertical wall 3 o is provided in which a notch 3 n can be formed.By inserting the cable 9 in the notch 3 n, it is possible to increasethe capability of retaining the cable 9. In an array of the ribs 10A,10B, and 10C, the rib 10C is located closest to the center (the centerof the side surface 6 c of the display device 6). Therefore, the load onthe rib 10C is distributed and is likely to be lighter than that on therib 10A. Thus, even if a gap gf of the notch 3 n is smaller than thegaps ga and gb, it is possible to reduce damage to the cable 9.

With the vertical wall 3 o in which the notch 3 n can be formed, the gapgf smaller than the other gaps ga and gb can be relatively easilyobtained regardless of the relative positions of the outer wall 3 g andthe rib 10 c.

As described above, according to the embodiment, the electronic device 1comprises the housing 3 a, the outer wall 3 g, the ribs 10A, 10B, and10C, the cable 9, and the protrusion 3 i. The housing 3 a houses atleast part of the display device 6 as an electronic component therein.The outer wall 3 g forms at least part of the outer contour of thehousing 3 a. The ribs 10A, 10B, and 10C are located between the outerwall 3 g of the housing 3 a and the display device 6, and the outersurface 10 b of them faces the inner surface 3 j of the outer wall 3 g.The cable 9 is located between the outer wall 3 g and the ribs 10A, 10B,and 10C. The protrusion 3 i is provided to the housing 3 a and stops therib 10A as a stopper. With this, if the display device 6 relativelymoves toward the outer wall 3 g by some cause such as the fall of theelectronic device 1, the protrusion 3 i prevents the rib 10A which ispressed by the display device 6 from being inclined outside of where thecable 9 is routed. Thus, protection for the cable 9 can be improved.Moreover, the stopper can be formed with a relatively simple structureas the protrusion 3 i located outside the rib 10A.

According to the embodiment, the housing 3 a comprises the firstdivisional body 3C and the second divisional body 3M. The firstdivisional body 3C is provided with the outer wall 3 g and the ribs 10A,10B, and 10C, while the second divisional body 3M is provided with theprotrusion 3 i as a stopper. This structure can be applied to a housinghaving a plurality of divisional bodies such as the second body 3 of theelectronic device 1. With this, a structure in which the rib 10A isstopped by the protrusion 3 i can be relatively easily obtained byassembling the first divisional body 3C with the second divisional body3M after routing the cable 9 in a recessed portion surrounded by theouter wall 3 g, the ribs 10A, 10B, and 10C, and the bottom wall 3 d ofthe first divisional body 3C. Especially, in the structure in which theouter wall 3 g and the ribs 10A, 10B, and 10C are provided on the bottomwall 3 d of the first divisional body 3C, the cable 9 is routed in therecessed portion surrounded by the outer wall 3 g, the ribs 10A, 10B,and 10C, and the bottom wall 3 d, and the protrusion 3 i is formed onthe top wall 3 e of the second divisional body 3M, the protrusion 3 i islocated on the edge side of the rib 10A. Thus, the protrusion 3 i is notlikely to interfere the cable 9 routed on the bottom wall 3 d side inthe recessed portion.

According to the embodiment, the second protrusion 3 m is provided tothe second divisional body 3M inside the outer wall 3 g of the firstdivisional body 3C as a second stopper that engages the outer wall 3 g.When the display device 6 that relatively moves outward presses theprotrusion 3 i through the rib 10A, the second protrusion 3 m engagesthe outer wall 3 g of the first divisional body 3C, thereby preventingthe protrusion 3 i from moving to the outside. Thus, it is possible toreliably achieve the effect of preventing the inclination of the rib 10Aby the protrusion 3 i.

According to the embodiment, at least part of the inner surface 3 j ofthe outer wall 3 g that faces the outer surface 10 b of the ribs 10A,10B, and 10C is formed flat. The flat inner surface 3 j prevents thecable 9 from being concentrically-loaded, thereby improving theprotection for the cable 9.

According to the embodiment, the reinforcing rib 10 c is formed on theouter surface 10 b of the ribs 10A and 10B as a reinforcing memberincluding a convex portion. Meanwhile, the inner surface 3 j of theouter wall 3 g that faces the outer surface 10 b is formed flat. Thisincreases the rigidity and the strength of the ribs 10A and 10B as wellas improving the protection for the cable 9.

According to the embodiment, the ribs 10A, 10B, and 10C are provided sothat the gaps ga, gb, and gc between them and the outer wall 3 g aredifferent in size. The outer wall 3 g is partly recessed at a portionfacing the rib 10B with the small gap gb as the recessed portion 3 p.This facilitates linear alignment of the rib 10A with the large gap gaand the rib 10B with the small gap gb, and also prevents the load fromelectronic components from concentrating on specific one of the ribs10A, 10B, and 10C.

According to the embodiment, the ribs 10A, 10B, and 10C are linearlyaligned spaced apart in a plan view from the direction in which the ribs10A, 10B, and 10C are raised (the Z direction). The display device 6 asan electronic component is arranged so that the side surface 6 c thereoffaces the inside of an array of the ribs 10A, 10B, and 10C. Theprotrusion 3 i is provided as a stopper correspondingly to at least therib 10A located at the end of the array. The protrusion 3 i prevents theinclination of the rib 10A that is located at the end of the array andmay be loaded most heavily. Thus, it is possible to effectively preventdamage to the cable 9.

According to the embodiment, the ribs 10A, 10B, and 10C are provided sothat the gaps ga, gb, and gc between them and the outer wall 3 g aredifferent in size. The ribs 10A, 10B, and 10C are linearly alignedspaced apart in a plan view from the direction in which the ribs 10A,10B, and 10C are raised (the Z direction). The display device 6 as anelectronic component is arranged so that the side surface 6 c thereoffaces the inside of an array of the ribs 10A, 10B, and 10C. Among theribs 10A, 10B, and 10C, the rib 10B with the small gap gb is located ata middle position of the array except for the ends. Since the rib 10Bwith the small gap gb is located at a middle position of the arrayexcept for the ends where the load acting from the display device 6 islikely to be lighter, it is possible to increase the capability ofretaining the cable 9 as well as to prevent damage to the cable 9.

According to the embodiment, the ribs 10A, 10B, and 10C are provided sothat the gaps ga, gb, and gc between them and the outer wall 3 g aredifferent in size. The display device 6 as an electronic component isarranged so that the side surface 6 c thereof faces the inside of anarray of the ribs 10A, 10B, and 10C. The plurality of cables 9 arearranged in parallel in the direction along the outer surface 10 b orthe inner surface 3 j, more specifically, in the direction in which therib 10B is raised, at least between the outer wall 3 g and the rib 10Bwith the small gap gb. This prevents an increase in the size of thehousing 3 a with respect to the size of the display device 6 viewed fromthe Z direction. By reducing the size of the gap gb with respect to eachof the cables 9, it is possible to increase the capability of retainingthe cable 9.

While the electronic device 1 of the embodiment is described above byway of example as a notebook personal computer, it may be any otherelectronic device than a notebook personal computer. Besides, the ribsmay be arranged to face another side surface of the display device. Theribs may also be arranged correspondingly to another electronic devicethan the display device. The specification (location, size, shape,direction, etc.) can be changed as required for the outer wall, theribs, the stopper, the second stopper, the electronic component, thereinforcing member, and the like.
